P11D deadline approaching and nothing is in order?
For most employers, P11D reporting sits at the bottom of the to-do list until it cannot be ignored any longer. Benefits were provided throughout the year without anyone keeping a running record, the correct cash equivalent values are unclear, and the 6 July deadline has a way of arriving faster than expected. A missed or incorrect filing means an automatic HMRC penalty — and, if Class 1A NI is underpaid, interest on top.
- No record kept of which benefits were provided to which employees
- Uncertain whether private medical, company car, or loan benefits are reportable
- Class 1A National Insurance liability calculated incorrectly or not at all
What a handled P11D looks like
We gather the benefit information, apply the correct HMRC valuations, calculate Class 1A NI, and submit both P11D and P11D(b) on time. You get a clear summary of what was reported and what is owed — no guesswork, no last-minute panic.
- Every benefit identified, valued correctly, and recorded against the right employee
- Clear guidance on what is and is not reportable before we start
- Class 1A NI liability confirmed in writing so you know what to budget for
- Fixed transparent pricing — get a quote before we start, no surprises on the bill
What employers say about us
Business owners who came to us for payroll and compliance work. The common thread is clarity — knowing what was filed, why, and what comes next.
I highly recommend Prads and Wings Online Filings! They were professional, responsive, and prompt throughout, and handled our company accounts and tax return smoothly. Excellent service and genuinely reliable, exactly what you want in an accounting partner.
Absolutely brilliant service. Prads is so efficient and knowledgeable. For the first time I feel well supported and informed over my self assessment returns and tax advice in general. Thank you!
Everything covered in the P11D service
One fixed price covers preparation, valuation, calculation, and HMRC submission — with a plain-English summary included as standard.
P11D Preparation and Filing
We prepare individual P11D forms for each employee or director in receipt of benefits in kind, applying the correct HMRC valuations for company cars, private medical insurance, interest-free loans, and other reportable benefits. Both P11D and the employer’s P11D(b) declaration are submitted to HMRC before the 6 July deadline.
Included as standardClass 1A NI Calculation
Class 1A National Insurance is calculated on the total value of taxable benefits and confirmed to you in writing before the 19 July payment deadline. You will know exactly what is owed and when it needs to be paid — no estimate, no assumption.
Included as standardBenefits Advice and Exemptions Review
Not every benefit needs to go on a P11D. We review what was provided and advise which items are covered by exemptions — trivial benefits, salary sacrifice arrangements, and employer-funded items that qualify for relief. The result is an accurate filing, not an over-reported one.
Included as standardConsistent results across different businesses
From directors managing a handful of employees to growing teams across multiple industries — the feedback covers speed, clarity, and confidence in the work.

Why employers choose us for P11D
P11D filing is one of those annual obligations that is straightforward when handled correctly and expensive when it is not. Here is what makes the difference.
Deadline managed, not chased
The 6 July P11D deadline and the 19 July Class 1A NI payment deadline are tracked for you. We contact you ahead of time for the information we need — you do not need to remember dates or chase reminders. Surprises are largely avoidable when someone is keeping an eye on the calendar.
Correct valuations, not estimates
Benefits in kind have specific HMRC valuation rules — company car benefit depends on list price, CO2 emissions, and fuel type; loans use official rates; accommodation has its own calculation. We apply the correct method for each benefit rather than a rough figure, which is the difference between a clean filing and an HMRC query.
Plain price, no hidden add-ons
Wings Online Filings is the best priced online accountancy practice in the UK. The quote you receive before we start is the price you pay — P11D preparation, P11D(b), Class 1A NI calculation, and HMRC submission are all included. Show us a lower quote from another practice and we will match it.
Up and running in four steps
Most clients are set up and have their P11D in progress within a few days. The process is straightforward and the information we need from you is minimal.

We gather the benefit details
Once instructed, we send a straightforward checklist of the information we need — company car details, private medical premiums, loan balances, and anything else relevant. Most clients have this to hand in a single email.
We prepare and review everything
We apply the correct HMRC valuations, calculate Class 1A NI, and prepare both the P11D forms and the P11D(b) employer declaration. Before filing, we share a summary for your review so nothing goes to HMRC without your sign-off.
Filed, confirmed, done
We submit to HMRC and send you confirmation of filing. You will have a clear record of what was reported, what Class 1A NI is owed, and when to pay it. Which is, frankly, the way it should be every year.
“Professional, efficient, confidence that everything is taken care of.”
Common questions about P11D filing
What exactly is a P11D and who needs to file one?
A P11D is the form employers use to report expenses and benefits in kind provided to employees or directors that are not put through payroll. If you have provided anything of value — a company car, private medical insurance, an interest-free loan, gym membership, or living accommodation — HMRC requires a P11D for each relevant person. The employer also submits a P11D(b), which is the declaration and Class 1A National Insurance summary. The filing deadline is 6 July following the end of the tax year.
How much does P11D filing cost and what is included?
Pricing is based on the number of employees with reportable benefits and the types of benefits involved, so we provide a fixed quote before starting. The quote covers preparation of all P11D forms, the P11D(b) employer declaration, Class 1A NI calculation, HMRC submission, and a plain-English summary of what was filed. Wings Online Filings is the best priced online accountancy practice in the UK — show us a lower quote from another firm and we will match it.
We have not kept great records of benefits provided this year. Can you still help?
Yes, and this is fairly common. We will work through what information you have — payslips, insurance schedules, car lease agreements, loan statements — and identify what is needed to complete the forms accurately. Where records are genuinely incomplete, we will tell you what we can and cannot confirm rather than guessing, because an incorrectly valued benefit can attract an HMRC query long after the filing deadline.
Is there a long-term contract? What if I just need P11D filed this year?
No long-term contract. P11D filing can be instructed as a one-off annual service, and many clients use us for this alongside their year-end accounts and payroll. If you only need P11D handled this year, that is perfectly fine — you will receive the same standard of work regardless. If you decide to move your broader accounting to us afterwards, we will make that transition straightforward.
Does payrolling benefits in kind mean we no longer need to file a P11D?
If you have registered with HMRC to payroll your benefits in kind, those benefits are included in employees’ pay and taxed through PAYE — meaning you generally do not need to submit individual P11D forms for the payrolled benefits. You still need to submit a P11D(b) to declare your Class 1A NI liability, however. If you are unsure whether your benefits are payrolled correctly or whether a P11D is still required, we can review your setup and confirm what needs to be filed.
Can we reduce the Class 1A NI cost by structuring benefits differently?
Some benefits are exempt from Class 1A NI altogether — certain trivial benefits under £50, employer pension contributions, and benefits covered by a PAYE Settlement Agreement, for example. Where salary sacrifice arrangements are set up correctly, some benefits can also be structured to reduce the NI cost to both employer and employee. We will flag any straightforward opportunities when preparing your P11D rather than leaving planning to a separate conversation.
